MACHINE FOR SPINNING OR DOUBLING YARNS AND THREADS.

Application filed December 9, 1922.

To all iii/20212 it may conceive:

lie it known that T, FRED FERRAND, a subject of the King of Great Britain and Ireland, and a resident of Southport, in the county of Lancaster, England, have invented certain new and useful Improvements in Machines for Spinning or Doubling Yarns and Threads, of which the following is a specification.

This invention has reference to spindle apparatus for yarn spinning and doubling machines, of the kind in which the yarn is spun or doubled and wound on a spindle by the rotation of a positively-driven ring flyer surrounding the spindle, which latter is rotated by the pull of the yarn and is given a reciprocal travel to build up the wound yarn into a cop or bobbin.

The object of the invention is to provide an improved ring flyer for spindle apparatus of the kind referred to.

in the accompanying drawings Fig. 1 is a vertical section of one form of ring flyer in accordance with the invention, and Fig. 2 is an elevation of same at right angles to Fig. 1.

Referring to the drawings, 5 is a ring flyer mounted in ball hearings in a fixed rail 6 and through which extends the spindle 7 which is rotatably mounted in a copping rail 8. The ring flycr 5 has an unobstructed internal diameter sufficient to allow the cop 9 which is built up on the spindle, to pass through it.

The ring flyer 5 is mounted in the fixed rail 6 so as to extend both above and below same, as shown. Above the rail, the upper end 5 of the ring fiyer is of conical formation and is formed with diametrically opposite lugs 10 provided with eyes 10 for leading the yarn to the spindle 7 and into which the yarn is passed by slits 10". Below the rail 6 the lower end of the ring flycr is provided with a whorl 11 whereby the ring tlyer is driven from a tin roller 12 by a band 12 as in a ring spinning frame.

The copping rail 8 is given a vertical reciprocation and progressive descent by means of mechanism similar to that employed for operating the ring rail of an ordinary ring frame.

in operation, the yarn is passed into one or other of the eyes 10 accordingly as twist-way or weft-way yarn and cops are to be produced and the direction of rotation of the ring fiyer 5. The yarn is spun Serial No. 605,813.

and wound on the spindle 7 by the positive rotation. of the ring flyer' 5 and the cop 9 is and spindle is equally applicable to the doubling of spun yarns and threads and to the combined operations of spinning and doubling, as to spinning alone.

The driving of the ring flyer, and the leading of the yarn or thread to the spindle, on oppositesides of the fixed rail in which the ring flyer is mounted produces a balancing effect which enables the ring flyer to be run at high speed with perfect balance, the absence of anything in the nature of fiyers or long arms reduces ballooning to a minimum and prevents undue strain being put upon the yarn or thread, thereby reducing breakages, with the. result that level yarns or threads are produced. The clear bore of the ring flyer prevents the lodgment and accumulation of fly or dirt therein, and the conical upper surface of the ring flyer forms an efficient finger surface for stopping the ring flyer by hand, while the short axial length of the ring flycr enables it to be applied to existing ring frames to convert same to operate in the manner described.

Preferably a machine will be provided with ring flyers and spindles at either side of a central creel as in a ring frame, and the tin rollers of the two sets of ring flyers will be separately driven, though one set may be driven by gearing from the other as in a ring frame.

What I claim as my invention and desire to secure by Letters Patent is 1. In machines for spinning or doubling yarns and threads, according to the method referred to, a positively-driven ring mounted in a stationary rail so as to project above and below same, said ring being driven at its lower end below the rail and being provided at its upper end above the rail, with an eye for conducting tl e yarn or thread to the spindle which is rotatably mounted so as to be rotated by the pull of the yarn or thread and is given a vertical reciprocation and progressive descent or rise to build up the yarn or thread into a cop or bobbin thereon.

2. In machines for spinning or doubling yarns and threads, 21 ringaccording to the preceding claim having its upper portion above the fixed rail of conical formation, substantially as and for the purpose de scribed.

53. In ya n spinning or doubling machines, a ring fiver mounted in stationary rail. said ring tlj'er being driven at its lower end and being provided at its upper end with means for leading the yarn to the spindle and with a conical surface adapted to serve as a finger-braking surface.

4. In yarn spinning or doubling inachines, a stationary rail, a ring flyer rotatably mounted in said rail, having a somewhat conical flutter-braking surface and an aperture through which a spindle may pass and to which the yarn is guided by the ring. and means for rotating the flyer.

In witness whereof I have hereunto set my hand.

FRED FERRAND.
